Buy O'Reilly iPhone Apps for Cheap eBooks

Want a cheap O'Reilly programming book? Buy the iOS App from iTunes (it doesn't matter whether you have an iPhone or not, and most of their books are $3-$5 as apps) and simply unzip the .ipa file on your computer.

Poke around in the folders, and you'll find the whole text of the book stored as plain html files — ready for reading on any device or computer.

You might even find an easter egg like I did in my PHP5 book. Upon unzipping it, I found an epub version of The Adventures of Alice in Wonderland ... presumably to just eat up space and make the app appear bigger.

The best way to do this is right click on the app in your iTunes library, show it in the Finder or Windows Explorer, copy it somewhere, change the extension to .zip, and then unarchive it.

Add Music to iTunes Remotely with Dropbox

Sometimes I'm not at home when I find some music I'd like to download. I've got a folder setup in Dropbox from which my Mac at home automatically pulls music and adds it to iTunes using the "add to iTunes" action. It allows you to add to the library, or into a specific playlist as well.

Use a 27" iMac as an External Monitor

If you want to hook up your MacBook to your iMac, you're usually out of luck without special software—but it turns out that the 27" aluminum iMacs only require a Belkin MiniDisplay port to MiniDisplay port cable. Just plug one end into your laptop, the other into your iMac, and you can use it as an external monitor!

I'm switching from Beta to Developer in hopes of getting the latest updates in the OS despite the instability.
